Where these are used

CCTV installers use this pack for camera mounting, junction box fixing, cable clips, and general structured cabling accessories. The countersunk head means fittings sit flush rather than proud, which matters where a bracket needs a clean finish against a wall or ceiling. The pozi recess is designed to reduce cam-out — the bit slipping out of the screw head — during driving, so it's suited to power tool use as well as hand drivers.

Zinc plating gives corrosion resistance, which is useful where fixings are exposed to damp air, such as loft spaces or unheated outbuildings, though the pack itself is intended for general indoor and protected fixing work rather than direct outdoor exposure.

Pair with matching plastic wall plugs when fixing into masonry rather than timber.
